| Abstract: | A Powdery and rapidly dissolved APAA with Ultra-high mol. -wt. has been prepared by inverse suspension and heterogeneous hydrolysis polymerization. Factors influencing hydrolysis degree (HD ) of PAA,such as pH. temperature. The ratio of V_(H_2O)V_(-OH)and n_(NaOH)/n_(AM) have been studied. Also the viscosity of APAA solution and the methods of ■ measurement have been discussed． |
